Which changes would result in a decrease in the gravitational force between two objects? check all that apply.

increasing the distance between the objects
decreasing the distance between the objects
increasing the mass of one of the objects
increasing the mass of both objects
decreasing the mass of one of the objects
decreasing the mass of both objects

The gravitational force between two objects is calculated through the equation, 
                                 F = Gm₁m₂ / d²
where F is the force, G is constant, m's are the masses and d is the distance between them. In order to lessen the force between them, the distance between them should be increased, decreasing the mass of one of the objects, and decreasing the mass of both objects. 

The answers that apply are;

decreasing the mass of both objectsdecreasing the mass of one of the objects increasing the distance between the objects

The formulae for gravity is; Gravity (g) = GM/R^2;

G is the gravitational constant ( 6.67 × 10^-11)

M is the mass of the planet (in kg)

R is the radius of the planet (in m)

When two objects are pulling on one another then the formula for the gravitational force between them is;

F = (G*m1*m2)/r^2

Therefore, as observed, the gravitational forces are inversely proportional to the distance between the objects and directly proportional mass of the two objects
